Voice Selection

The p255 presents a total of 24 voices, not an impressive amount, in fact depending on the sort of player you are you will either find this satisfying or disappointing.

  • String
  • 2 Bass
  • Pad
  • Choir
  • Others

  • Room

  • Hall2
  • Stage

  • Medium
  • Hard
  • Fixed

The p-255 is equipped with a wide range of drum patterns that vary in readme and style (jazz, rock, country, pop, classical, reggae etc), in addition to this it offers 24 Demo Songs and 50 Piano Preset Songs.

One of the best features in the Yamaha p-255  is the ability to record, users can record up to 10 pieces and play them back at any time. Such a feature will enable teachers to record a certain piece and have their students listen to it over and over again.

This recording feature allows you to :

  1. Record both hands separately
  2.  Set an A-B Repeat configuration
  3. Start/Stop with sustain  pedal
  4. change Voice & tempo after recording

Sound Boost 

Provides the ability to further increase the fullness of the sound with the touch of a button, you can easily make the sound of the P-255 louder and enhance its presence. This feature will prove itself useful while playing for a singer, or even playing in a band. Sound Boost allows for a clear-sounding performance that will cut through any mix. Works both on the internal speaker as well as the external speakers.

256 Polyphony Note

Polyphony is the number of notes a piano can play at once by holding the sustain pedal.The p255 allows a total of 256 notes, this is a high amount for a digital piano.

Having a 256 polyphony notes count is a game changer, expressiveness on digital pianos have always been good, but this model is personally raising the competition bar.

This polyphony count makes it a good candidate for professional players, even intermediates.

Beginners will not able to tap into the full benefit of this high polyphony at first, but by improving this will prove vital; Above is a polyphony graph that simply illustrates this concept with a graphically.

Key Action

The P-255 uses the graded hammer action (GH), this is an advanced technology that gives the piano keys the right weight, a weight that is eventually distributed proportionally along the piano bed.

One of the pros of this weighted instrument as to do with its keys, the keys material have been upgraded to Synthetic Ivory rather than plastic, giving it an edge over its competitors.

I bought this for my husband as a Christmas present. He has the same version just 15 years older. These products last and last. His older one was still working but I wanted to surprise him with updated technology and it did not disappoint. He loves it. He almost cried when he opened it

Yamaha keyboard piano review (2)

Although I am new to the piano, I did a lot of research prior to buying the Yamaha P255 and I am very pleased and convinced I made the right choice.Mark

This digital piano is a complete advancement from its predecessor as it is specifically targeted for advanced/intermediate players. I believe The Jazz and Classical players will love this. Due to its price budget might be an issue, as the price of this musical instrument is very high, nevertheless, this can be considered a long-term investment into your piano career, as You will hardly ever want to upgrade from this digital piano. While this product will not offer a workstation experience like some of other Yamaha digital pianos, this is more of a switch on, and play a digital grand piano experience.When compared to the other Yamaha P pianos, there is no doubt this is the best one.
